Hi there,
I found a strange bug that is reproducible in your demo application!

The iGrid control crashes when an editable text cell is selected in the iGrid and you press the ^ key and then any other key!

Steps to reproduce:
- Open the iGridDemo.exe
- Start for example 'Cell Merging Simple Demo'
- Select a cell
- Press the ^ key twice in a row !!

This leads always to the following error:

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
bei TenTec.Windows.iGridLib.iGrid.StartTextBoxEdit(Int32 rowIndex, Int32 colIndex, String text, Char keyChar)
bei TenTec.Windows.iGridLib.iGrid.RequestEditCellInternal(Int32 rowIndex, Int32 colIndex, Char keyChar, Boolean openDropDown, Boolean doDefault)
bei TenTec.Windows.iGridLib.iGrid.OnKeyPress(KeyPressEventArgs e)
bei System.Windows.Forms.Control.ProcessKeyEventArgs(Message& m)

bei TenTec.Windows.iGridLib.iGrid.WndProc(Message& m)
bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Please fix it ;)

Greetings, Peter
Do you mean the '^' character (Shift+6) or the Up Arrow key or what? I can't reproduce the bug.

Can you record a screen video demonstrating that?
Peter Schilling
I mean the ^ key or the ° key if you preffer this more ;)

You can find it below the ESCAPE-Key or left of the 1 or above the TAB-Key..

And the error dows only occur if you start the edit mode.

There is no error if you are already in edit mode ..
On my keyboard this is the backwards apostrophe or grave accent (`), and pressing it does not lead to the bug you reported.

you really got a different Keyboard-Layout in Ukraine then?

Can you please install the german or english keyboard-layout and switch to it?

You will be able to reproduce this bug then!

This key is always very special in germany because the first stroke does not produce a readable sign, but the second does ..

I just reproduced this bug with the english keyboard layout and the same key as well!

Hello Igor,

I just arrived at home and produced a video for you wich demonstrates this bug..

I hope this helps?! 
Oh, I've managed to reproduce that bug. However, on my keyboard it does not occur in the English layout. I needed to install the German keyboard, and the bug appears only when I try to enter a character with an accent by pressing the Above-Tab key first.

Give me some time to investigate this issue. I hope I'll come up with a solution in a day or two.
We investigated this issue. The issue occurred not only with the circumflex mark (^) while using German keyboard layouts, but in similar situations for other locales. For example, for the accent mark in Spanish in which letters like á and é can be entered. The problem was fixed in the v6.0.37 we have just published on the website.

Expand the spoiler below if you are interested in the details of the problem.
